Abstract: A peristaltic pump is disclosed. The peristaltic pump comprises a tube platen; and a plunger (see 3091, figure 277) configured to actuate toward the tube platen (3022). An end of the plunger has a rounded end and a bottom of the tube platen has a generally U shape that provides a radial gap between the plunger and the tube platen about equal to two to three times a wall thickness of an infusion tube. The rounded shapes of the plunger tip and tube platen avoid compressing the walls of the infusion line (3210), thereby reducing the compressive load on the plunger (see also paragraph [00943]).

Abstract: A flow meter, comprising: a coupler adapted to couple to a drip chamber; a support member operatively coupled to the coupler; a first image sensor having a first field of view and operatively coupled to the support member, wherein the first image sensor (337) is positioned to view the drip chamber within the first field of view; a second image sensor (338) having a second field of view and operatively coupled to the support member, wherein the second image sensor is positioned to view the drip chamber within the second field of view; and at least one processor operatively coupled to the first and second image sensors, wherein: the at least one processor receives a first image data from the first image sensor and a second image data from the second image sensor, and the at least one processor estimates at least one parameter of liquid within the drip chamber using the first and second image data.

Abstract: A peristaltic pump and a method of operating an infusion pump are disclosed. The peristaltic pump comprises, a pump housing, a door pivotally coupled to the pump housing having a platen disposed on an inner portion of the door, a cam-follower shaft disposed within the housing, a cam shaft disposed approximately parallel with the cam-follower shaft, a first cam disposed on the cam shaft to rotate with the cam shaft, a first cam follower pivotally coupled to the cam-follower shaft, the first cam follower having an active end configured to actuate toward the door when closed against the housing, the first cam follower also having a follower end configured to engage with the first cam, a second cam disposed on the cam shaft to rotate with the cam shaft, a second cam follower pivotally coupled to the cam-follower shaft, the second cam follower having an active end configured to actuate toward the door when closed against the housing, the second cam follower also having a follower end configured to engage with the second cam, a third cam disposed on the cam shaft to rotate with the cam shaft, wherein the third cam is disposed between the first and second cams on the cam shaft, a third cam follower pivotally coupled to the cam-follower shaft, the third cam follower having an elongated active end which is elongated relative to at least one of the first and second cam follower active ends and configured to actuate toward the platen when the door is closed against the housing, the third cam follower also having a follower end configured to engage with the third cam, and a spring coupled to the third cam follower to bias the follower of the third cam follower against the third cam. The third cam follower and third cam are configured such that as the elongated active end actuates away from the platen, the third cam actuates the third cam follower away from the cam shaft.

Abstract: A medical device according to the invention comprises a user interface having a front side and a backside the user interfacing including a touchscreen sensor; an antenna 5034 disposed in parallel with and adjacent to a surface defined by the back side of the user interface; and a frame 5035 surrounding the touchscreen sensor and having a gap 5104 such that the frame defines a split-ring resonator disposed in spaced relation to the user interface and configured to operate with the antenna, wherein the split-ring resonator is not in direct conductive contact with the antenna. Provision of such a medical device enables a user to modify and customise various programming options in order to improve safety and efficiency.
